Commit Message

- No change in rootfile
- Changelog
2026b
Briefly:
British Columbia moved to permanent -07 on 2026-03-09.
Some more overflow bugs have been fixed in zic.
Changes to future timestamps
British Columbia’s 2026-03-08 spring forward was its last
foreseeable clock change, as it moved to permanent -07 thereafter.
(Thanks to Arthur David Olson.) Although the change to permanent
-07 legally took place on 2026-03-09, temporarily model the change
to occur on 2026-11-01 at 02:00 instead. This works around a
limitation in CLDR v48.2 (2026-03-17). This temporary hack is
planned to be removed after CLDR is fixed.
Changes to code
zic no longer mishandles a last transition to a new time type.
zic no longer overflows a buffer when generating a TZ string like
"PST-167:59:58PDT-167:59:59,M11.5.6/-167:59:59,M12.5.6/-167:59:59",
which can occur with adversarial input. (Thanks to Naveed Khan.)
zic no longer generates a longer TZif file than necessary when
an earlier time zone abbreviation is a suffix of a later one.
As a nice side effect, zic no longer overflows a buffer when given
a long series of abbreviations, each a suffix of the next.
(Buffer overflow reported by Arthur Chan.)
zic no longer overflows an int when processing input like ‘Zone
Ouch 2147483648:00:00 - LMT’. The int overflow can lead to buffer
overflow in adversarial cases. (Thanks to Naveed Khan.)
zic now checks for signals more often.
